Methods of Stabilisation: Zygomatic fractures |
|
¨ Osteosynthesis ¨ Antral support ¨ External pin fixation ¨ Internal pin fixation
Osteosythesis ¨ Miniplate fixation at F-Z suture ¨ Microplate fixation at Infra-Orbital rim ¨ Miniplate fixation at zygomatic buttress ¨ Microplate fixation at zygomatic arch ¨ Transosseous wires less rigid and less stable
Antral Support ¨ Rarely used ¨ Gross comminution of zygoma and antral walls ¨ Antral pack of gauze soaked in Whiteheads Varnish ¨ Antral balloon ¨ If comminuted orbital floor ? Risk of displacement of bony fragment and trauma to optic nerve
External Pin Fixation ¨ Frontal-Zygomatic sutures ¨ Pin placed in body of zygoma ¨ Pin placed in supra-orbital ridge ¨ Pins connected rigidly by vertical rod and universal joints
Internal Pin Fixation ¨ Transnasal K wire—opposite unfractured zygoma used as stable base to rigidly hold fractured zygoma via transversely placed K wire ¨ Removal at 3—6 weeks
